The 7 Best RV Roof Coatings: Weatherproof Your RV For Less

Last Updated on

Keeping your RV in tiptop shape is just as important as buying the right RV for you. One of the things that an RV owner should maintain is its roofing.  As such, rubber roofs are often preferred over those made in aluminum and fiberglass because they are lightweight and cheap.  Whatever you decide, you’ll want to make sure you get the best RV roof coating.

You must realize, however, that the initial layer on RV roofs will wear off over time, which is normal. And regardless of your roofing material, giving it a liquid coating is a must.

An RV roof coating will give your roof a nice sheen and shield it from harmful ultraviolet rays and other harsh elements. It becomes a protective barrier, which will prolong the lifespan of your RV, making it more durable even with frequent use.

However, going to the store to buy one can be daunting, especially if you don’t know what you should be looking for in the first place.  It is important to determine which qualities must be taken into consideration before grabbing the first tub that you see.

What you need to know

I have come up with the following tips that could help you ensure that you are buying the right coating for your RV roof.

Check what your RV roof is made of

Does your RV have a rubber roof or a fiberglass one?  Knowing your roof material is the deciding factor in choosing the appropriate liquid coating.

Roof coating composed of TPO (or Thermoplastic Polyolefin) or EPDM (Ethylene Propylene Diene Terpolymer) is suitable for rubber roofs.  Then there are liquid coatings that are formulated with polyester to cater to other types of roofing like fiberglass as well as aluminum.

Fiberglass roof is heavier just like an aluminum roof, but more expensive. Both types, however, require low maintenance compared to rubber roofing.

Check the roof coating’s DIY factor

When you see the liquid coating in the store, which resembles a paint coating, you’d want the same application process as well.  In other words, you can apply it like you’re just painting over a surface.

So you will be looking for a roof coating that can be applied using an extended brush, squeegee, or a roller.  Sometimes just like with regular paint, a primer will be required for a smoother finish.  Ultimately, you should be able to do the task yourself and it’s important that it should be an easy application.

Check the insulation and reduction of thermal flux features on your roof coating

As you know, RVs are often exposed to the sun’s rays especially during summer.  It is best if your roof coat provides additional insulation and can also reduce heat flow from roof to ceiling.  This will make your stay inside as cool and comfortable as possible.

Another benefit of this feature will be on your AC’s efficiency.  When you get extra insulation from your liquid coating,  your AC will not have to work extra hard to cool the cabin.  This will mean savings on electricity or gas depending on your AC’s power source.

Check how fast the coating will cure

Curing is critical.  When your RV roof has observed the proper curing time, you will have a good, solid coating that’s ready to rock and roll. You definitely don’t want to mess this up.

Essentially, cure times will vary among different brands and types of liquid coating, which will range from 2 days to as long as 7 days.  You must note that weather can be a factor, too.

Summer is a good time to apply a roof coat because it can dry much faster compared to any other season.  You will be left with a shiny and beautiful coating that will last longer.

After reading all there is that you need to know about RV roof coating, it’s time to check out the brands you can choose from.    There’s just too many in the market so I have narrowed it down for you with only the best.  Let’s get right into it.

Heng’s Rubber Roof Coating Review

The positives: excellent coverage, waterproof, versatility, UV resistance, ability to prevent cracks, environment-friendliness, hassle-free usage

This is our top choice for a number of reasons.  While you can do just a single application, Heng’s Rubber Roof Coating covers the roof surface more evenly after two coats.  It comes with a bubble-free formula that will give your roof a flawless finish just like a good paint job.  This is why it applies easily to the RV rubber roofing.

The Heng’s Rubber Roof Coating also doubles as a sealant for your rubber roofs, seams, and tears.  What’s more is that it can even seal your AC unit and vent.  You can take advantage of its capacity of 1 gallon at an affordable price.  As such, it can provide full roof coverage for a camper that is 25 feet long.

This coat binds nicely to a rubber roof.  When you need to clean it up after application, it does quite easily.  As soon as it’s been fully dried and cured, its outer durability is very impressive.

Other roof maintenance tips for your RV

For you to get the most out of your RV, create a habit of inspecting your RV especially before storing it in your garage or embarking on a road trip.  Aside from giving it a fresh coat, regular checks on the roof, in particular, are necessary so problems, if any, can be caught in their early stages.

  1. Get a visual of your RV roof surface by using a ladder instead of just climbing on top of it so that you’ll be able to hose any dirt off.  This is because it can be slippery as the roof material can’t support any considerable weight above it.  Cleaning the roof surface should be done at least every 3 months, or more if your RV is always parked under a tree.
  2. Before anything, don’t forget to refer to your RV manual to determine the cleaning procedure recommended for your roof.  It is not uncommon to stay away from the harsher chemicals like those that contain citric acids, abrasives, and solvents, which cannot be used on rubber surfaces.  Once you have picked the right cleaning agent, scrub using a sponge or soft brush and rinse off until no trace of cleaner can be found.
  3. Give your roof a careful scan for any cracks, punctures and any sign of deterioration and seal them right away.  Doing this will keep moisture away from your RV, which otherwise can bring mold and mildew that can be health hazards as well.

Conclusion

I hope you have learned a lot from the above for you to make an informed decision.  Ultimately, any RV owner will like to enjoy their vehicle for a long time, making many memorable trips in the process. So never take your roof maintenance for granted to make this possible.  Go and pick out the right roof coat for your RV.
